If you have the discord app (or however that works) you can join the TTV game night group, then look under the pinned items and there are links to the skins. There is probably also a link somewhere in this topic.

So I found almost all of the landmarks except the Kini Nui pathway and Midak's lab. Oh well! Still had a blast playing on this server and discovering all of the Easter eggs, even if I didn't screenshot them properly. It was great to see the fruits of TTV's labor and I can't wait for another opportunity to do this again (survival/Koro-based factions?).
